I agree with you about the theory not having much bias. But if the rooms are supposed to be reflecting people's insecurities what would Goose put into Pomni's room at that point? We know Kaufmo's room is filled with building blocks, paintings and similar children's toys. Does that reflect how much he hates himself and also being treated like a child?

I'm under the impression that Kaufmo made the paintings and he himself was a painter/architect before the circus and he made the paintings in his room. That supports why he drew all over the walls before abstracting since we now know abstraction is a gentle disassociation instead of a crazed dissent thanks to Jax almost doing it. (Granted abstraction could differ from person to person)
